COMBINED BISCUIT AND DOlJGHNUT CUTTER.

SPECIFICATION forming part Of Letters Patent No. 730,792, dated June 9, 1903.

Application filed February 7,1903. Serial No. 142,399. (No model.)

To aZZ whom it may concern):

Be it known that I, NATHAN A. OLIVER, a

citizen of the United States, residing at Mattapoisett, in the county ofPlymouth and State ofMassachusetts, have invented new and useful Improvements in a Combined Biscuit and Doughnut Cutter, of which the following is a specification.

My invention relates to new and useful improvements in a combined biscuit and doughnut cutter; and its object is to provide a device of this character which may be readily converted from a biscuit-cutter to a doughnut-cutter and which has means for cutting;

and removing the central portion of the doughnut.

The invention consists in providing a cylindrical body portion, the lower edge of which is adapted to cut the biscuit or doughnut fromthesurroundingdough. Slidablymounted within the top of the body portion is a small cylindrical cutter, which is normally removed from the lower edge of the body and incloses'a device which is employed for removing from said small cutter any dough which may accumulate therein.

The invention also consists in the further novel construction and combination of parts hereinafter more fully described and claimed, and illustrated in the accompanying drawings, showing the preferred form of my invention, and in which- Figure 1 is a side elevation of my improved cutter. Fig. 2 is a vertical transverse sec tion therethrough, and Fig. 3 is a section on line 3 3 of Fig. 1.

Referring to the figures by numeralsofreference, 1 is a cylindrical cutter, the upper portion of which is closed, as shown at 2, and is provided at the center with a depending cylindrical portion 3, closed at the bottom and having a coiled spring 4 arranged therein and extending from the upper portion thereof. Guides 5 are arranged upon opposite sides of that portion of cylinder 3 which extends above the top 2, and within these guides are mounted slides 6, which extend through apertures 7, formed at the lower ends of the guides, and are connected at their lower ends to a ring 8, which incloses and is slidably mounted upon the cylinder 3. A handle 9 connects the upper ends of slide 6 and bears upon the upper end of spring 4:. By means of this handle the slides may'be forced downward, thereby removing the ring 8 from the lower end of cylinder 3, as shown in dotted lines in Fig. 2. Spring 4 is also compressed by this operation,and as soon as the handle 9 is released said spring will return the parts to normal position. Apertures 10 are formed in the guides 5 and in the opposite sides of cylinder 3. These apertures are in horizontal alinement, and apertures 11 are formed in the slides (i and are adapted when said slides are in normal position to register with apertures 10. Pins 12 can be inserted in the apertures 10 and 11 and will the guides 5. These pins may be connected by means of a flexible strip 13 or in any other suitable manner.

When it is desired to use the device for cutting biscuits, the pins 12 are placed in engagement with slide 6, and the ring 8 is therefore prevented from traveling downward into the center of the biscuit. In cutting doughnuts the pins 12 are removed, and when the cutter'is brought down upon the dough the ring 8 will be carried downward into the center of the doughnut, and as soon as the handle is raised that portion of the dough out by the ring 8 will be carried upward until it is brought into contact with the a lower end of cylinder 3, when it will be discharged automatically therefrom.

In the foregoing description I have shown the preferred formof my invention; but I do not limit myself thereto, as I am aware that modifications may be made therein without departing from the spirit or sacrificing any of the advantages thereof, and I therefore reserve the right to make such changes as hold the slides 6 against movement within pending into said body portion and having its lower end closed, a cutting-ring slidably mounted upon the cylinder, and means for holding said ring normally removed from the cutting edge of the body.

3. In a cutter of the character described, the combination with a body portion having a cutting edge; of a cylinder depending Within the body and having its lower end closed, a cutting-ring slidably mounted upon the cylinder, a handle, slides connecting the handle and ring, and a spring hearing at opposite ends upon the cylinder and handle, whereby the ring is held normally removed from the cutting edge of the body.

4. In a cutter of the character described, the combination with a body portion having a cutting edge; of a cylinder secured within NATHAN A. OLIVER.
